A third woman, reportedly a National Party member, said she has never been "more harassed and disrespected as a woman in my whole life" after dealing with Mr Ross.

She said she stayed quiet "out of respect for the party", but had to talk after Mr Ross' denials of wrongdoing in his hour-long press conference on Tuesday.

"This man is a narcissist. He absolutely turns on people when he doesn't get his own way. He is a master manipulator and a deceitful liar who has no problem looking somebody in the eye and outright lying."

The fourth woman says Mr Ross "destroyed" her as a person, and she had to seek help for the stress and anxiety he allegedly caused.

"I lost my self-esteem... I lost everything."

Mr Ross did not respond to Newsroom's request for a response. Newshub has contacted Mr Ross.

Earlier this week he said Mr Bridges and Ms Bennett had accused him of harassing four women - the exact number quoted in the Newsroom article. Mr Bridges allegedly told him that number could be increased to 15.

On Tuesday, Ms Bennett told NZME the leadership team raised issues with Ross - but it wasn't about harassment.

"At no point was the matter of sexual harassment ever put to Jami-Lee Ross," Bennett told NZME. "What was put to him was inappropriate behaviour that is unacceptable from a married Member of Parliament."
